Summary: Injection volume and column volume overload are common issues in miniaturized chromatography. Optimal injection volume balancing chromatographic efficiency and sensitivity is crucial. Experimental results show that volume overload in isocratic elution can decrease chromatographic efficiency, while a reduction in peak capacity in gradient elution is only observed when the injection volume exceeds 40% of the effective column volume.

Summary: Analytical expressions for retention time and peak compression factor are deduced by assuming quadratic solvent strength model and multilinear gradient elution. A program for the optimization of multilinear gradient profile is written and applied to search for a gradient profile for the separation of twelve compounds that are degraded from lignin. Results show that a better separation of the compounds is achieved under an S-shaped multilinear gradient profile than that obtained under linear gradient profile.

Summary: This study demonstrates that microalgae can utilize sodium bicarbonate as an inorganic carbon source to enhance carbon dioxide fixation rate and algal biomass production. By employing a smart intermittent bicarbonate feeding strategy, biomass concentration can be further improved. Additionally, bicarbonate promotes self-flocculation and the formation of extracellular polymeric substances, leading to enhanced nutrient uptake and gas exchange, thus improving biomass production and self-settling. This innovative approach can be scaled up to efficiently sequester flue-gas CO2 released by thermal power plants and other fossil fuel-based industries through algal cultivation.

Summary: This study focuses on the recovery of sinapic acid using liquid-liquid extraction assisted by a hollow fiber membrane contactor from an aqueous feed obtained through the hydrolysis of mustard bran. The screening of solvents of different chemical nature showed that all tested solvents had an extraction efficiency of more than 80% for pH < 5. Four solvents were selected for use in the hollow fiber membrane contactor, and the volatile solvents showed higher mass transfer coefficients compared to non-volatile solvents. The extraction efficiency was intensified by increasing the initial concentration of sinapic acid and the feed-to-solvent ratio. CPME was found to have optimal recovery efficiency at a phase ratio of 8:1, yielding 0.9 g of sinapic acid per liter of CPME used.

Summary: In this study, a nanofibrous layered structure of Ff-Ti3C2Tx-Co3O4 was prepared by self-assembling nanofibrous Co3O4 with lamellar fluorine-free MXene (Ff-Ti3C2Tx). The Ff-Ti3C2Tx-Co3O4 exhibited excellent catalytic activity for degradation, resistant to ionic interference, and maintained high removal efficiency of sulfamethoxazole (SMX) in municipal wastewater. The rapid SMX degradation involved fast electron transfer in redox cycles with PMS and the generation of 1O2 via PMS ->center dot O2 -> 1O2. This work provides new insights into antibiotic degradation mechanisms and electron transfer based on PMS activation.

Summary: In this study, sludge-derived biochar (SBC) was functionalized with various iron salts to enhance its adsorption ability for sulfamethoxazole (SMX) and magnetic collection performance. Ball milling was further employed to treat the optimal iron salt functionalized SBC (MSBC), resulting in ball milled SBC (BMSBC) with improved adsorption performance for SMX. The dominant driving mechanism for SMX adsorption onto BMSBC was confirmed to be multiple physicochemical forces, including 7C-7C conjugation, pore filling, H-bonding, Fe-O complexation, and electrostatic interactions. BMSBC exhibited favorable adsorption ability for SMX in actual waters and could be easily collected within 1 min due to its magnetic sensitivity.
